Answer:
60
Step-by-step explanation:
The answer should be $21,840.50
Explanation:
20000*1.045=a (first year)
a*1.045=b (second year)
b = 21840.5
The answer is c. You double the number for finding radius
All's =a
Bob's =b
Lunar =l
A:B = 4:5 B:C = 6:7
Multiply the two ratios above by 6 and 5 respectively
A:B = 24:30 and B:L=30:35
Now that we have the B's to be the same
Alls:Lunar = 24:35
It really depends on what kind of problem. like if you are doing a word problem or whatever than you should read the question a couple times, underline key words, DECIDE which operation to use, refer to the question and see if it makes sense. Hope I helped :)
